    -------------------------------------------------------------------------     Debian LTS Advisory DLA-3664-1                debian-lts@lists.debian.org     https://www.debian.org/lts/security/                      Markus Koschany     November 24, 2023                             https://wiki.debian.org/LTS

    Package        : symfony     Version        : 3.4.22+dfsg-2+deb10u3     CVE ID         : CVE-2023-46734     Debian Bug     : 1055774

    Pierre Rudloff discovered a potential XSS vulnerability in Symfony, a PHP     framework. Some Twig filters in CodeExtension use `is_safe=html` but do not     actually ensure their input is safe. Symfony now escapes the output of the     affected filters.

    For Debian 10 buster, this problem has been fixed in version     3.4.22+dfsg-2+deb10u3.

    We recommend that you upgrade your symfony packages.

    For the detailed security status of symfony please refer to     its security tracker page at:
